TruGroove 6-Inch Hidden Door Hinge — Concealed Door Hardware, 180° Swing, 3-Way Adjustable (Black)

Discreet hardware that elevates your space

The TruGroove 6-inch Hidden Door Hinge is designed to disappear into the architecture while delivering smooth, dependable operation. With a concealed mounting and a black finish, the hinge lets the door sit flush with the wall, letting architectural lines shine without visible hardware. This design approach supports contemporary interiors, galleries, and premium renovations where an uninterrupted wall plane matters.

Three-axis adjustability for precise fitting

Installation is made straightforward. The hinge offers adjustments in three dimensions: vertical and horizontal up to ±2.5 mm, and depth up to ±1.1 mm. You can tweak alignment or depth without removing the door, helping you fine-tune the fit after installation.

• Vertical and horizontal alignment for exact gaps
• Depth control to accommodate wall irregularities
• Adjustment possible without disassembly for faster setup

Durable build and quiet, reliable operation

Constructed from a zinc-aluminum alloy with thoughtful internal geometry, these hinges resist wear and corrosion while delivering quiet, smooth motion. Each hinge supports a substantial door weight, with a pair handling up to about 88 pounds (40 kg) and enabling up to an 181° opening angle. The combination of materials and design aims for long-lasting performance in daily use.

• High-strength support per hinge (approx. 20 kg)
• Rust resistance for longer life
• Near-silent operation under typical use
